This invention relates to'utheart of paper rej ceptacles, and moreparticularly 'to individual par;

per cups of the type disclosed in my .United States Letters Patent No.1,8'70,223, .granted August 9, 1932. j

-An object of thisvinventio'n. is to rovidean improved cup of the openor self-extended type which is vbetter adapted'to resist any tendency tocollapse it during dispensing or use of the same.

Another object of the invention is to so improve aV cup oftheabove-noted type that the open end of the cup is forced to assume.a'shape which more nearly`approximates a circle.

A further object of the invention is to depress the wall bf a cup insuch a manner and at such points as to cause the cup tobe better able tore'- tain an open shape in condition for immediatel In accordance withthe general lfeatures of this invention,l there is provided ajcup havinga body t portion Vadapted when in use to present a substantially roundedmouth and being of open form,

'tapering' "from itsmouth in wedge-like 'shape to a tight bottom closuremade by a straight edge transverse fold-upof the cup material secured tothe'body portion, thewall of the body portion' iiedforms of cupsembodying features of the blank .shown in Figure 1.

invention, in one form of whichthel rib-like depressions extendsubstantially the' full length of the cup, Whereas. in`V the other formthe rib-like depressions do not extend the full length of the. cupbutare disposed in an intermediate position between the top and bottom ofthe cup.' f

Itis als'o the aim of this invention-to provide van.improved;method ofjmaking a cup having the foregoingfeatures. However, it is thought'tliat'Y my, novel method will be fully understood from v a description of a,cup

made as a result of the use of the method.

Other objects and features of this invention will more fully appear fromthe; following detailed '1. description taken in connection with theaccomy panying drawings, which 1ll us\trate-several-em bodimentsthereofLandin which wFigure l-isa view. of a'pap`er blank froniiw'hichmy novel cup i s made. Figure 2 is a top view o f a cup made hfrom theFigure 3 is a side view of'this cup. Figure 4' is a top view of thesamecup after the. cup has had opposite depressed ribs incorporatedtherein 'involving the features of this invention. v o Y Figure 5 is asideview of the cupshown in Figure'i.l 5

Figure e is a .v'1sw` of a mourned blank from which a cup. embodyingthis invention can also beconstructed.. m

Figure '1 is a side view of a cup maqerrom thel blank shown in Figure6,- and having depressed 1'0 modiiied orm of cup similar to that shownin Figure 5 but diifering erefrom in thatthe lonl5 gitudin n ribs do'note d the run length of thei cup. L

'.As shown o n the drawings:

The reference character- I0 designates geh-V' erally ablank which may bemade from paper 20 or any other suitable material and from which a cupembodying the features of my invention is adapted. tovbe constructed.blank has convegingside edges gli and I2 which attheir outer extremityterminates in avcurvededge |315 adapted to denne the rounded mouth ofthe cup.

'Theinner extremities of the side edges II and I2' .terminate in afold-up portion designated generallyby 'the reference character I4. Thisfoldup Ais adapted tol be folded about transverse liles 30 'offoldindicated by dotted lines and designated I5 and I'I'to the line I6,the lin'esHIS and I1 will 40.

bedirectly over the line I64 when the `blank is folded intoI awedge-shaped cup. When thus vfolded, they will define a transversestraight-edge I8 (Figure 3) at'the bottom of the cup. VThis, edge I8will 'be located at theline It (Figure 1). 45 l The portions of the cupblank between the lines A|5516 and 'I1 and-the bottom extremity ofthecup comprisesin 'reality a plurality of superimposed layersin theresulting fold-uli. Il' shown in' Figure 1: .The portions of the cupwhich are 50 adapted to be thus formed in superimpod layers tion 20 of'the fold-up has an extension or adhesive tab 22. In other-words, thelayer or por- 55 tion constitutes an exterior layer `which is llightlylonger than the underlying layers i9 and :I'he side of theblank `Il) atthe edge l2 is provided with a strip of adhesive designated by thereference numeral 24. This marginal portion with the strip of adhesivethereon is adapted to be overlapped by theside portion ofthe blankadjacent the edge Ii and to be glued to that portion, as will be evidentfrom Figure 3.- Thereafter the fold-31p Il is turned upwardly about theline I6 and is glued to the side of the cup over the overlapped sideedges by means of adhesive on the tab 22.

This results in the cup being provided with a water-tight straight edgetransverse fold up at the bottom o! the cup.

In the formation of the cup from the blank lill the blank isl rolledupon any suitable apparatus such, for example, as a mandrel, into thewedgelike form shown in Figures 2 and 3. In this form the cup has arounded mouth and is creaseless. In other words it is oi a self-extendedopen i'orm tapering from its mouth in wedge-like form to the say, thesedepressions areformed in the cup asv far downy toward the bottom of thecup as the structure 'will permit without distorting or damaging thebottom closure. 'Ihese depressions are diametrically opposite and areformed in the diametrically opposite narrow sides I3 yand il o! the cupshown-in Figure 2. In Figure 2 it will be perceivedl that the cup has anelliptical cross-` sectional shape. It is at the narrow sides Il and 34i' this cup oielliptical cross-sectional shape that I form thedepressions Il and 3| shown in Figures 4 and 5.

These depressions, may be formed by any suit- V able apparatus. I nndthat they may be incorvso porated in the cup by disposing the cup over amandrel of proper cross-sectional shape and by thereafterrunning ribbingfingers over the edges 33 and 34 of the cup. In carrying out thisoperation the pressureon the sides or edges 33 andl u of the cup pressesthese ,narrow end sides or edges inwardly so that,the open end of thecup is caused to assume a shape which more nearly approximates that of acircle. In other words.

.the cup is opened to a still further extent so that,-

it is in effect changed from a cup having an open end of an ellipticalcrpss-section to `a cup having an end of substantially a circularcross-section as shown .in Figure 4. y

In Figures 6 and 7 I have illustrated a modified iormo'f theV inventionin which the'principal dii'- ference resides in the change of thelocation ot the adhesive tab 22 as well yas the location oi' the stripof adhesive 24. The `cup in this form. oi the invention is made from ablank it having converging side edges Il' and I2' terminating at theirouter ends.in the lcurved edge i3' ior deilningthe open end ofthe cup.'Ihe inner extremities of' these side edges terminate in a foldup I4'made up of three plies, the outer layer of form an extension or tab 22.This fold-up is folded about the transverse straight edge I8' as shownin Figure 7.

In this form of the invention the extension taby '22', instead of beingformed in a central position with reference to the side edges, is formedadjacent one of the side edges li so as to in effect constitute anextension of that side oi the blank.

This enables a single strip of adhesive 24' to be applied in asubstantially straight line along the side edge Il" and also on theextension tab 22. f

In Figure 8 I have illustrated a modiiica'tionv of the first form' ofthe invention in which the only dierence resides in the fact that theribs length of the cup butterminate below 4the open g end of the cup asindicated at and Il. With this exception this form oi.' the invention islike the form shown in Figure 5. i

Iam aware that many changes may be/made and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I, therefore. do not purposelimiting the patent granted hereon otherwise -than necessitated by theprior art.
